Description :
New detailed data about the morphology of the submerged slopes of Lake Albano have been collected by a sonar multibeam survey. These data allow for investigation of the subaqueous slope dynamics of the lake, which partially fills a volcanic depression, and the elucidation of the relationships between subaqueous and subaerial slope processes. The AA. propose a classification based on the landslide's size and type of movement. They recognized rock fall/topples, debris flows, rock slides and slump, complex rock slides/channelled flows and debris slide and slump. Two main landslide hazard scenarios have been depicted and discussed from the results of the integrated analysis of both subaerial and submerged gravity-induced landforms.
